Know anything about Rogers LS7?


I was just clearing out an old storage unit and found a set of Rogers LS7s. They look brand new. Don't know much about them or if they are worth keeping or selling. Anyone have an ideas?

Beautiful speaker from the 1980s. Use a clean powered amp and good stands. Very revealing, lightly warm sounding. Box resonances can be excited easily so keep away from walls. Really for large rooms. I ran the slightly smaller 6a.
